The configuration of HAProxy is divided into five parts. Of course, these components are not mandatory and can be selected as needed. Global: The parameter is process-level, usually related to the Operating System (OS. These parameters are generally set only once. If the configuration is correct, you do not need to modify defaults again: to configure the default parameter, which HAProxy Configuration The

Comparison of haproxy lvs nginx Load Balancing For the software that implements load balancing, let's take a look at it in detail. In terms of performance and stability, LVS is the best, basically reaching 60% of the performance of F5 hardware equipment, and other 10% are a little difficult. However, the configuration is also the most troublesome because of LVS, and the Health Check requires configuring Ldirector. Other

Today, a colleague came to me and said that their new website ulinux.img.bkjia.com.cn could not be accessed. The Code returned from the page was a test machine. My first response was a DNS resolution problem and dig was normal, no request for the header ulinux.img.bkjia.com.cn is sent when you log on to the backend web packet capture service. I caught a lot of results on the testing machine that my colleagues said. At this time, the haproxy rule shou
